LockDockBar is a free alternative to IntelliScreen

LockDockBar is an application that displays 4 icons on your locked screen: SMS, Calls, Emails, Calendar. The app displays the notification badges for each app so if for example you have a new email, you will see this notification next to the email icon. From there, instead of unlocking the phone and launching the mail app, you simply tap the mail icon from your lock screen and it takes you there directly.

I think it is a great and free alternative to Intelliscreen, and it works perfectly with Status Notifier.
